I don't like how short the middle segments are on those example displays. There's no reason they can't have squarer top and bottom edges. The diagonals don't have double-beveled ends.

This one runs down some other designs for a 14 segment display and also has 16 segment displays (where all of the cross-bars are split in 2 instead of just the middle)
